Mono-types aren't actually competitively valid. They just aren't, so all those comments aside, I congratulate you for trying to put together a mono-type team, which is very difficult to use in the standard OU environment.

All comments bashing monotypes aside, (which isn't your fault at all) I noticed that you have a LOT of boosting sweepers, and a hyper-aggresive team in general. An issue with this is because you have the same type, you won't have the time to switch in on something and get in a boost as it switches out like with standard teams. Also, you don't have many speedy pokes. Latios can outrun every member of this team, and shred it with a powerful specs psychic or draco meteor.

Psychics and fliers are a massive threat to this team, as it is a mono. You need a counter to psychics, such as scrafty, which can switch into something such as espeon and potentially set up.

Watch your teambuilding! Some of your pokemon don't have items or natures, such as Virizion, missing a nature and an item, and Hitmonchan, missing a nature. Use a nature!

Choiced pokemon could see some use on the team as well, as your team needs instant speed and power, which it has neither as of now.
